Objectives: This study was conducted as descriptive correlation research in order to survey healthcare personnel(HCP)'s awareness of patient safety culture and their recognition of standard precautions, and to examine the correlation between the two factors. Methods: The subjects were 400 HCPs including 80 doctors, 240 nurses, and 80 medical technicians from two general hospitals. The questionnaire used in the survey consisted of 9 questions on general characteristics, 44 on the perception of patient safety culture, and 21 on the recognition of standard precautions. Results: According to the subjects' general characteristics, the score was significantly higher in those aged over 40 than in those aged 30-39. In addition, it was significantly higher in managers than in practitioners, in those with work experience of less than a year than in those with 5-9 years. The score was also significantly higher in those working 8 hours a day than in those working over 10 hour a day. The number of medical accident reports according to the subjects' general characteristics was significantly larger in nurses than in doctors, in managers than in practitioners, and in those with 10 years' or longer experiences than in those with less than a year. In the awareness of standard precautions according to the subjects' general characteristics, the score was significantly higher in female workers than in male workers, and in managers than in practitioners. As a whole, the subjects' awareness of patient safety culture and their recognition of standard precautions showed a significant correlation with each other. Conclusion: From the result of this study, sufficient work force and the promotion of organizational culture for safety is needed in order to guarantee patient safety. Likewise, these results suggest that experience, job skill, and adequate working hours have a positive effect on the awareness of patient safety culture and the recognition of standard precautions.

Introduction: It is a challenge to design a protein score function which stabilizes the native structures of many proteins simultaneously. The coarse-grained description of proteins to construct the pairwise-contact score function usually ignores the backbone directionality of protein structures. We propose a new two-body score function which stabilizes all native states of 1,006 proteins simultaneously. This two-body score function differs from the usual pairwise-contact functions in that it considers two adjacent amino acids at two ends of each peptide bond with the backbone directionality from the N-terminal to the C-terminal. The score is a corresponding propensity for a directional alignment of two adjacent amino acids with their local environments. Results and Discussion: We show that the construction of a directional adjacency-score function was achieved using 1,006 training proteins with the sequence homology less than 30%, which include all representatives of different protein classes. After parameterizing the local environments of amino acids into 9 categories depending on three secondary structures and three kinds of hydrophobicity of amino acids, the 32,400 adjacency-scores of amino acids could be determined by the perceptron learning and the protein threading. These could stabilize simultaneously all native folds of 1,006 training proteins. When these parameters are tested on the new distinct 382 proteins with the sequence homology less than 90%, 371 (97.1%) proteins could recognize their native folds. We also showed using these parameters that the retro sequence of the SH3 domain, the B domain of Staphylococcal protein A, and the B1 domain of Streptococcal protein G could not be stabilized to fold, which agrees with the experimental evidence.

In this paper, we propose a hybrid method which is mixed with frame selection and weighting model rank method, based on GMM(gaussian mixture model), for real-time text-independent speaker recognition system. In the system, maximum likelihood estimation was used for GMM parameter optimization, and maximum likelihood was used for recognition basically Proposed hybrid method has two steps. First, likelihood score was calculated with speaker models and test data at frame level, and the difference is calculated between the biggest likelihood value and second. And then, the frame is selected if the difference is bigger than threshold. The second, instead of calculated likelihood, weighting value is used for calculating total score at each selected frame. Cepstrum coefficient and regressive coefficient were used as feature parameters, and the database for test and training consists of several data which are collected at different time, and data for experience are selected randomly In experiments, we applied each method to baseline system, and tested. In speaker recognition experiments, proposed hybrid method has an average of 4% higher recognition accuracy than frame selection method and 1% higher than W method, implying the effectiveness of it.

Objectives: The purpose of this study was to find out the fear of dentist care, subjective recognition of dental health, and quality of life in the male high school students and to analyze the influencing factors on dental health care. Methods: A self-reported questionnaire was filled out by 243 special high-school in Deagu province from March 3 to March 14, 2014. The questionnaire consisted of general characteristics of the subjects(5 questions), subjective recognition of health and activities to improve health(6 questions), dental fear(20 questions), oral health related quality of life(16 questions). The instrument for dental fear was adapted from measured by Berggren Dental Fear Survey(DFS). A total of 20 DFS questions included treatment avoidance(8 questions), stimulus reaction(6 questions), and physiological reaction(5 questions) and score by Likert 5 scale. Cronbach alpha was 0.974 in the study. Oral health related quality of life was measured by 16 questions of CPQ11-14 for the adolescents by Lau. CPQ11-14 consisted of oral symptoms(4 questions), functional restriction(4 questions), and emotional wellbeing(4 questions). The instrument was score by Likert 5 scale and Cronbach alpha was 0.9354 in the study. Data were analyzed using SPSS 18.0 program for ANOVA and multiple regression analysis. Results: Fear of dentist care showed significant differences in treatment avoidance factor(p<0.001), stimulus reaction factor (p<0.05), and physiological reaction factor(p<0.001). The factors depended on subjective recognition of health and health-improving activities and differences in treatment avoidance factor(p<0.05) and physiological reaction factor(p<0.01). The dental symptoms factors showed significant differences in health recognition(p<0.001), interest in health(p<0.001), alcohol drinking status(p<0.001) and regular meal(p<0.001). While function limit factors showed differences in health recognition (p<0.001), interest in health(p<0.001), smoking(p<0.001), alcohol drinking(p<0.001) and regular meal(p<0.001). Mental and social stabilities factors showed significant differences in health recognition(p<0.001), interest in health(p<0.001) and alcohol drinking status(p<0.001). Among the factors influencing on the quality of life in dental health, interest in health(p<0.005), alcohol drinking(p<0.005) and physiological reaction in the midst of fear of dentist care(p<0.001) were the significant impact factor. Conclusions: It is necessary to develop a continuous and systematical program of dental health and dental care by experts so that the students can reduce the fear of dentist care by regular dental checkup and preventive treatment and care.

This study is the descriptive survey for the purpose of providing the basic data that establishes the strategy to promote adolescent's hope by the examining of self-esteem, academic achievement, family functioning and hope of adolescents and the investigating of the factors influencing the hope in adolescents. The subjects for this study were 456 students of the first and second year of man's senior high school that located in Seoul. The data were gathered from 16th to 31st of the October 2000. For the survey tool, it was used that the Family Assessment Device(FAD) of Epstein, Baldwin & Bishop(1983), the Self-Esteem Inventory(SEI) of Coopersmith(1975), the class record order and Hinds & Gatusso(1991)'s Hopefulness Scale for Adolescents(HSA). The collected data was analyzed by statistics methods as the descriptive and frequency analysis, t-test, ANOVA, Pearson and Spearman correlation coefficients and Stepwise multiple regression of SAS program. The results of this study were following : 1. The mean score of self-esteem of young people was 51.06±6.83 and the mean grade was 2.04. The high academic achievement was 29.2％, middle grade was 52.7％, and low grade was 18.1％. The mean score of the family functioning was 38.30±6.98 and the mean grade was 2.25. The mean score of hope was 84.26±16.45 and the mean grade was 3.51. 2. The hope in adolescents was significantly different according to their father's school career. The mean score of the group that the father's school career was below junior high school was 77.32. That was significantly lower than the mean score 84.59 of the group that the father's school career was above college and the mean score 85.18 of senior high school group(F=4.04, P= 0.0183). 3. The self-esteem was represented the positive correlation with family functioning(r=0.43) and the all of the 4 subscales(r=0.31, 0.41, 0.39, 0.30). And, it was highly ranked as much as family functioning was good. The academic achievement was represented the positive correlation with self-esteem(r= 0.15). Also, the positive correlation was shown between the affective responsiveness, role recognition and emotional support as the subscales of family functioning and academic achievement(r=0.11, 0.12). And so, academic achievement was high as much as self-esteem was high and affective responsiveness and role recognition and emotional support were good. The hope was represented positive correlation with self-esteem and academic achievement(r=0.42, 0.26), and with the whole of family functioning(r=0.15) and the 4 subscales(r=0.13, 0.16, 0.11, 0.13). So, hope was high as much as self-esteem was high, academic achievement was high and family functioning was good. 4. The influencing factors on the hope of adolescents were self-esteem(17.63％), academic achievement(3.41％), father's school career(0.84％). These factors made it possible to explain 21.88％ of hope.

Purpose: The purpose of this study was to compare the cardiac knowledge and symptoms recognition between men and women with acute coronary syndrome (ACS). Methods: Cross-sectional survey research design and convenience sampling were used in this study. 64 men and 42 women from a university medical center were participated in this study. Data collection were used with self reported questionnaires and medical records. Results: There was no difference in cardiac knowledge by gender. Women marked the higher score in symptoms recognition than men. Significant gender differences were observed in the reports of several symptoms (headache, nausea, palpitation, hand paresthesia, and leg numbness) and with ACS. There was significant correlation between cardiac knowledge and symptom recognition on both men and women. Conclusion: These findings suggest that health care professionals should pay attention to the differences in clinical symptoms between women and men. Furthermore, tailored information about possible symptoms of coronary artery disease according to the patient's gender is needed.
